Re: [PHP-DB] Any method to get primary key matching a given value ?

Hi Ratin,

working with sqlite, are you ?

In that case, take a look at the default table :

SELECT sql from sqlite_master where type= "table" and name = 
"<your_table_name>"

This query returns the creation query of the table concerned.
By parsing it textually, you can find out the field name that was 
declared PRIMARY (key)
